Technical fundamentals often determine Grand Slam success, and serving consistency has emerged as a critical factor for several top contenders. Coco Gauff’s 42 double faults in three Canadian matches highlight how mechanical issues can derail championship ambitions regardless of other strengths.
The serve remains tennis’s most important shot, and players struggling with this fundamental aspect face significant challenges in best-of-three-set matches. Gauff’s 23 double faults against Danielle Collins represent nearly a full set’s worth of free points, illustrating the devastating impact of serving problems.
Professional coaching changes often occur when technical issues require immediate attention. Gauff’s decision to part ways with Matthew Daly suggests recognition that serving problems need urgent resolution before the season’s final major championship.
Success at the U.S. Open traditionally requires strong serving performance, particularly on the faster hard courts of Flushing Meadows. Players who can maintain serving consistency while handling pressure situations typically emerge as the tournament’s strongest contenders and eventual champions.
